Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding rod heat preservation cylinder for preventing power failure. Background Art

[0002] During the construction stage of nuclear power plants, due to a large number of on-site cross-constructions, there are situations such as sharing and moving of three-level distribution boxes. When welders and fire watchers start working, they often focus their attention on the working points and easily neglect the state of the welding rod heat preservation cylinder. The power supply line of the welding rod heat preservation cylinder occasionally fails to be restored in time after a power failure. If it cannot be discovered in time, the temperature inside the cylinder gradually decreases, and finally the temperature of the welding rod will be lower than the standard working temperature range. The performance of the welding rod below the standard working temperature range deteriorates. When in use, it not only affects the welding quality, but also may cause insufficient strength of the welded structure, increasing potential safety hazards. In addition, for welding rods below the standard temperature range, they need to be redried when used again to achieve ideal process performance. Multiple bakings will not only reduce the performance of the welding rods, but also increase the construction cost. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" any variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] Figure 1 is a schematic structural view of the first electrode holding cylinder provided according to the present utility model. This embodiment is applicable to the scenario of monitoring the power-off situation of the electrode holding cylinder. Such as Figure 1As shown, the electrode holding cylinder includes: an electric heating circuit (not shown in the figure), and the electrode holding cylinder further includes a circuit detection module 1, a control module 2, and an alarm module 3. The circuit detection module 1 includes a circuit status information acquisition end 11 and a circuit status information output end 12, the control module 2 includes a circuit status information receiving end 21 and an alarm instruction output end 22, and the alarm module 3 includes an alarm instruction receiving end 31. The circuit status information acquisition end 11 is used to acquire the working status information of the electric heating circuit. The circuit status information output end 12 is electrically connected to the circuit status information receiving end 21, and the alarm instruction output end 22 is electrically connected to the alarm instruction receiving end 31. The control module 2 is used to determine the working status of the electric heating circuit according to the working status information received by the circuit status information receiving end.

[0043] Specifically, as Figure 1 shown, the circuit status information acquisition end 11 of the circuit detection module 1 is arranged close to the electric heating circuit to acquire the working status information of the electric heating circuit. Among them, the working status information can be the current information or temperature information of the electric heating circuit. The circuit status information output end 12 of the circuit detection module 1 is electrically connected to the circuit status information receiving end 21 of the control module 2 to transmit the circuit status information to the control module 2, and the control module 2 determines the working status of the electric heating circuit according to the circuit status information. Among them, the current information can be the current signal value, the temperature information can be the change of temperature, and the working status can be the power-off state or the power-on state. Further, when the electric heating circuit is in the power-off state, there is no current signal. The absence of current means that the heating element in the electric heating circuit no longer has an energy source and cannot continue its heating function, and the temperature naturally drops. Therefore, when the current signal value is zero, it is determined that the electric heating circuit is powered off, or when the temperature drops, it is determined that the electric heating circuit is powered off. When the control module 2 determines that the electric heating circuit is in the power-off state, it generates an alarm instruction. The alarm instruction output end 22 of the control module 2 is electrically connected to the alarm instruction receiving end 31 of the alarm module 3 to transmit the alarm instruction to the alarm module 3. The alarm module 3 issues an alarm prompt according to the alarm instruction to remind the staff that the electrode holding cylinder is powered off, so that the staff can restore the power supply of the electrode holding cylinder in time, prevent the temperature of the electrode from being lower than the standard working temperature range, ensure the performance of the electrode, and the performance of the electrode has an important impact on the welding quality during the welding process. Preventing the electrode holding cylinder from being powered off can ensure that the electrode is within the standard temperature range, which is crucial for the stability of the welding process and the quality of the weld.

[0044] In the embodiment of the present utility model, the working state of the electric heating circuit is determined by monitoring the circuit state information of the electric heating circuit. When the electric heating circuit is in a power-off state, an alarm prompt is issued, which is convenient for the staff to discover the power-off situation of the electrode holding cylinder and restore power supply in time. On the one hand, it prevents the temperature of the electrode from being lower than the standard working temperature range, ensures the performance of the electrode, and thus improves the welding quality. On the other hand, it avoids increasing the baking times of the electrode and reduces the construction cost.

[0045] On the basis of the above embodiment, this embodiment further describes the temperature detection unit of the circuit detection module. Figure 2 FIG. 5 is a schematic structural diagram of a second type of electrode holding cylinder provided according to an embodiment of the present utility model. The circuit detection module 1 includes a temperature detection unit 100; the circuit state information acquisition end 11 includes a temperature information acquisition end 101, the circuit state information output end 12 includes a temperature information output end 102, and the circuit state information receiving end 21 includes a temperature information receiving end 201; the temperature information acquisition end 101 is used to acquire the temperature information of the electric heating circuit, and the control module 2 is used to determine the working state of the electric heating circuit according to the temperature information received by the temperature information receiving end.

[0046] Specifically, as Figure 2 shown, the electric heating circuit heats the electrode through a heating element, and the heating element can be an electric heating wire. When the electric heating circuit is powered off, the current no longer flows through the electric heating wire. Since the heating principle of the electric heating wire is to convert electrical energy into heat energy (generate heat through the resistance's hindrance to the current), the interruption of the current means the stop of heat generation, and the temperature naturally drops. Therefore, when the temperature drops, it can be determined that the electric heating circuit is in a power-off state. Further, a temperature detection unit 100 is provided to monitor the temperature of the heating element in the electric heating circuit in real time. Since the circuit state information output end 12 is connected to the circuit state information receiving end 21, and the circuit state information output end 12 includes a temperature information output end 102, and the circuit state information receiving end 21 includes a temperature information receiving end 201. Therefore, the temperature information output end 102 is connected to the temperature information receiving end 201 to transmit the temperature information to the control module 2. If the temperature of the electric heating element decreases, at this time, the control module 2 can determine that the electric heating circuit is in a power-off state according to the temperature information.

[0047] In this embodiment, by adding a temperature detection unit, the temperature of the heating element in the electric heating circuit is directly detected to judge whether the electric heating circuit is powered off. Compared with detecting the temperature inside the electrode holding cylinder, the detection accuracy is improved and the reliability of the judgment is increased.

[0048] On the basis of the above embodiment, this embodiment further describes the scheme for the circuit detection module to detect the current signal. Figure 3It is a schematic diagram of the third electrode heat preservation cylinder structure provided according to an embodiment of the present invention. The loop detection module 1 includes a current detection unit 1001; the loop status information acquisition end 11 includes a current information acquisition end 1011, the loop status information output end 12 includes a current information output end 1021, and the loop status information receiving end 21 includes a current information receiving end 2011; the current information acquisition end 1011 is used to acquire the current information of the electric heating loop, and the control module 2 is used to determine the working state of the electric heating loop according to the current information received by the current information receiving end 2011.

[0049] Specifically, as Figure 3 shown, the electrode heat preservation cylinder is heated through an electric heating loop. The power-off of the electric heating loop will affect the heat preservation function of the electrode heat preservation cylinder, thereby affecting the quality of the electrode. By detecting the current information in the electric heating loop, it is possible to judge whether the electric heating loop is powered off according to the current information. When the electric heating loop is in a power-off state, the current signal value is zero. Therefore, the current detection unit 1001 can be set to monitor the current information in the electric heating loop in real time. Since the loop status information output end 12 is connected to the loop status information receiving end 21, and the loop status information output end 12 includes a current information output end 1021, and the loop status information receiving end 21 includes a current information receiving end 2011. Therefore, the current information output end 1021 is connected to the current information receiving end 2011 to transmit the current information to the control module 2. If the current signal value in the electric heating loop is zero, the control module 2 can determine that the electric heating loop is in a power-off state according to the current information.

[0050] In this embodiment, by adding a current detection unit to directly detect the current signal in the electric heating loop to judge whether the electric heating loop is powered off, the detection accuracy is further improved and the reliability of the judgment is increased.

[0051] On the basis of the above embodiment, the embodiment of the present invention further describes the alarm module. Figure 4 It is a schematic diagram of the fourth electrode heat preservation cylinder structure provided according to an embodiment of the present invention. The alarm module 3 includes a flash alarm unit 32 and a sound alarm unit 33; the control module 2 includes a flash alarm instruction output end 221 and a sound alarm instruction output end 222, the flash alarm unit 32 includes a flash alarm instruction receiving end 321, and the sound alarm unit 33 includes a sound alarm instruction receiving end 331; the flash alarm instruction output end 221 is electrically connected to the flash alarm instruction receiving end 321, and the sound alarm instruction output end 221 is electrically connected to the sound alarm instruction receiving end 331.

[0052] As Figure 4As shown in the figure, the alarm instruction output terminal 22 includes a flash alarm instruction output terminal 221 and a sound alarm instruction output terminal 222. Among them, the flash alarm instruction output terminal 221 is electrically connected to the flash alarm instruction receiving terminal 321 of the flash alarm unit 32 to transmit the flash alarm instruction to the flash alarm unit and control the flash alarm unit 32 to give a light alarm prompt. The sound alarm instruction output terminal 222 is electrically connected to the sound alarm instruction receiving terminal 331 of the sound alarm unit 31 to transmit the sound alarm instruction to the sound alarm unit 33 and control the sound alarm unit 33 to give a sound alarm prompt.

[0053] Specifically, the flash alarm can be an alarm light strip, and the light strip is arranged around the electrode holding cylinder. Exemplarily, when the electrode holding cylinder is working normally, the light strip is green, and when the electrode holding cylinder is in a power-off state, the light strip shows red to remind the staff.

[0054] Furthermore, the sound alarm unit 33 can be a buzzer. When the electrode holding cylinder is in a power-off state, the buzzer emits a harsh alarm to attract the attention of nearby staff in a noisy scene.

[0055] In the embodiment of the present utility model, by setting the flash alarm unit and the sound alarm unit, a flash alarm reminder and a sound alarm reminder are given when the holding cylinder is powered off, reminding the staff in multiple ways that the electrode holding cylinder is powered off, so that the staff can timely restore the power supply of the electrode holding cylinder and ensure the quality of the electrode.

[0056] Furthermore, Figure 5 is the fifth structural schematic diagram of the electrode holding cylinder provided by the embodiment of the present utility model. The alarm module 3 further includes a remote alarm unit 34; the control module 2 further includes a remote alarm instruction output terminal 223, and the remote alarm unit 34 includes a remote alarm instruction receiving terminal 341 and a remote alarm information output terminal 342; the remote alarm instruction output terminal 223 is electrically connected to the remote alarm instruction receiving terminal 341, and the remote alarm information output terminal 342 is communicatively connected to a remote terminal (not shown in the figure).

[0057] Specifically, as Figure 5As shown, in order to facilitate the staff to understand the power-off and power restoration real-time situation of the electrode holder heat preservation cylinder on-site, text messages can be sent to the staff through mobile communication. Specifically, the alarm module 3 includes a remote alarm unit 34, where the remote alarm unit 34 includes a remote alarm instruction receiving end 341. The alarm instruction output end 22 of the control module 2 further includes a remote alarm instruction output end 223, the remote alarm instruction output end 223 is connected to the remote alarm instruction receiving end 341, and the remote alarm information output end 342 of the remote alarm unit 34 is communicatively connected to the remote terminal. So as to transmit the remote alarm instruction to the remote alarm unit 34 to control the remote alarm unit 34 to send out remote alarm information to the remote terminal through the remote alarm information output end 342. Among them, the remote alarm information can be the working state of the electrode holder heat preservation cylinder.

[0058] Exemplarily, if the electrode holder heat preservation cylinder is in a power-off state, the remote alarm unit 34 will send the power-off information of the electrode holder heat preservation cylinder to the remote terminal. If the electrode holder heat preservation cylinder resumes power supply, the remote alarm unit 34 will send the power restoration information of the electrode holder heat preservation cylinder to the remote terminal. Among them, the remote terminal can be a mobile phone, and the remote alarm unit 34 sends the working state information of the electrode holder heat preservation cylinder to the staff in the form of text messages through wireless communication. So that the staff can understand the power-on and power-off situation of the electrode holder heat preservation cylinder on-site in real time.

[0059] In the embodiment of the present utility model, a remote alarm unit is provided, and the power-on and power-off states of the electrode holder heat preservation cylinder are sent to the staff's mobile phone in the form of text messages through the remote alarm unit, so that the staff can understand the real-time situation of the working state of the electrode holder heat preservation cylinder on-site in real time.

[0060] On the basis of the above embodiment, this embodiment further describes the structure of the electrode holder heat preservation cylinder. Figure 6 is a side view of the electrode holder heat preservation cylinder provided according to an embodiment of the present utility model. Figure 7 is a top view of the electrode holder heat preservation cylinder provided according to an embodiment of the present utility model. As Figure 6 and Figure 7 shown, the electrode holder heat preservation cylinder further includes an electrode holder heat preservation cylinder body 4 and a base 5, and the electrode holder heat preservation cylinder body 4 is detachably arranged on the base 5; the loop detection module 1 and the control module 2 are arranged on the electrode holder heat preservation cylinder body 4; the electric heating loop is arranged inside the base 5, and the alarm module 3 is arranged on the surface of the base 5.

[0061] Specifically, as Figure 6As shown in the figure, a heat preservation cylinder body 4 is arranged on a base 5 for supporting the heat preservation cylinder body 4. The electrode heat preservation cylinder body 4 is detachably connected to the base 5, which facilitates the flexibility and adjustability of the electrode heat preservation cylinder and is conducive to improving the maintenance efficiency. Further, an electric heating circuit is arranged inside the base 5. In order to facilitate the detection of the working state of the electric heating circuit, a circuit detection module 1 and a control module 2 can be arranged at the bottom of the heat preservation cylinder body 4.

[0062] In addition, as Figure 7 shown, in order to facilitate the staff to clearly observe the working condition of the electrode heat preservation cylinder, an alarm module 3 can be arranged around the electrode heat preservation cylinder body on the surface of the base 5 to present different light colors to the staff, facilitating the staff to judge the on-off state of the electrode heat preservation cylinder.

[0063] Optionally, as Figure 6 shown, the electrode heat preservation cylinder further includes a power cord 6, a power cord clip 7 and a telescopic rod 8; the power cord 6 is electrically connected to the electric heating circuit; the power cord clip 7 is used to clamp the power cord 6 on the telescopic rod 8; the telescopic rod 8 is arranged above the base 5.

[0064] During the welding process, the power supply of the electrode heat preservation cylinder is mainly completed through the secondary voltage of the welding machine. Among them, the secondary voltage refers to the voltage output through the secondary power cord of the welding machine after being stepped down by the internal transformer of the welding machine. Therefore, the power cord 6 of the heat preservation cylinder is connected to the secondary power cord of the welding machine, taking the secondary voltage as the power supply. The power cord 6 of the heat preservation cylinder is electrically connected to the electric heating circuit to supply power to the electric heating circuit through the secondary voltage to obtain the required heating power. Thus, the electrode heat preservation cylinder maintains the stability of the internal temperature, enables the electrode to be in the standard temperature range for a long time to ensure the performance of the electrode, and further improves the welding quality.

[0065] Usually, the power cord has no protection measures and is easily torn off. By setting the spring clip 7 to clamp the power cord on the telescopic rod, when the power cord 6 is pulled, the spring clip 7 can relieve part of the force, thus preventing the power cord 6 from being torn off and causing the electrode heat preservation cylinder to lose power.

[0066] Optionally, as Figure 6 shown, the electrode heat preservation cylinder further includes a welding record module 9; the welding record module 9 is arranged on the telescopic rod 8 and is electrically connected to the control module 2.

[0067] Specifically, the welding record module 9 can be a welding video recorder. Due to the changeable on-site environment, it is objectively difficult for the staff to find a suitable position to place the welding video recorder. Fix the welding video recorder at the top of the telescopic rod 8 and adjust the welding video recorder to an appropriate height through the telescopic rod to record the welding process in real time.

[0068] Optionally, it further includes heat insulation cotton (not shown in the figure); the heat insulation cotton is arranged on the inner wall of the electrode holding cylinder body 4.

[0069] Specifically, the main function of the heat insulation cotton is to slow down the heat conduction speed through the inner wall of the holding cylinder, thereby significantly extending the heat preservation time of the electrode holding cylinder, which ensures that the electrode can be within the standard working temperature range for a long time, avoiding the decline of the electrode performance and affecting the welding quality. In addition, setting the heat insulation cotton can help the temperature inside the holding cylinder to be more evenly distributed, reducing the temperature unevenness caused by direct contact with the relatively cold cylinder wall, thus ensuring the consistency and stability of the electrode storage environment.

[0070] The above specific implementation manners do not constitute a limitation to the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
